Aromatic alcohol-lignin-aldehyde resins and processes for making and using same

Aromatic alcohol-lignin-aldehyde resins and process for making and using same. In some examples, a process for making a resin can include heating a first mixture that includes a lignin, an aromatic alcohol, and a base compound to produce a second mixture that can include an activated lignin, the aromatic alcohol, and the base compound. The second mixture can be heated with an aldehyde to produce a third mixture that can include an aromatic alcohol-lignin-aldehyde resin and unreacted free aldehyde. In some examples, an aromatic alcohol-lignin-aldehyde resin can be or include a co-polymer of an activated lignin, an aromatic alcohol, and an aldehyde. A weight ratio of the activated lignin to the aromatic alcohol can be about 20:80 to about 95:5.

Alkylphenol resins and a method of preparing thereof

Compositions, methods, and resins using alkyl aldehydes and phenols are provided herein. In one embodiment, a composition comprising an alkylphenol resin can be prepared by condensing at least one phenolic monomer selected from the group consisting of phenol, cresol, resorcinol, xylenol, ethyl phenol, alkylresorcinols, and combinations thereof; and at least one alkyl aldehyde having from 5 to 12 carbon atom alkyl groups. The alkylphenol resins of the application are free of octylphenol or nonylphenol monomers. In one embodiment, the alkylphenol resins may be prepared using formaldehyde, and alternatively, in another embodiment, the alkylphenol resins may be prepared without the use of formaldehyde. The process to make these new alternative alkylphenol resins is a cost effective process and easy to scale-up.
